. SPECIFICATION forming part of Letters Patent No, 741,463, dated October 13, 1903. l' Application filed August 11 1903. Serial No. 169,082. (No model.)

To all whom it may concern:

Be it known that I, JosErII CoUEvILLn, a citizen of the United States, residing'at Detroit, in the county of Wayne and State of Mich- Igan, have invented certain new and useful Improvements in Music-Rolls for Mechanical Players, of which the following is a specification,reference being had therein to the accompanying drawings.

rIhe invention relates to pneumatic players for musical instruments,and has more `particular reference to the rolls upon which the perforated music-sheets are wound. Y

In the present state of the art the width of music-sheet used in various constructions of pneumatic players is not uniform. In order to permit of using various widths of music on the same instrument, adjustable trackers have been provided which maybe adapted for use in connection with the various forms of music-sheet. It' is necessary that the winding roll, which is usually permanently attached to the player, should be of sufficient length to receive the widest music-sheet used on the instrument, and it is further necessary that provision should be made for guiding the music-sheets when wound upon said roll,so as to insure exact registration with the tracker.`

It is the object of the present invention to obtain a simple construction of music-winding roll, which is provided with adjustable guides adapted to cooperate with music-'sheets of various widths. v

To this end the invention consists in the construction as hereinafter set forth.

In the drawings, Figure lis an elevation of a music-winding roll to which my improvement is applied. Fig. 2 is a perspective view of* one end of said roll with the adjustable guide detached therefrom.

A is the music-winding roll, and B repre-r a, which are of such a width as to receive the iianges B. These flanges B are in the form of disks, preferably formed of metal and of a thickness to enter the kerf a and at thesame time to frictionally engage with the roll so as to be retained in position thereon. The disks are cut away at h to form a radial enteringslot of sufficientwidth to receive the uncut core o of the roll A.V The slot h terminates at its inner end in a rounded edge adapted toA fit around the core c and to hold the flange 13 concentric with the roll A.

Y With the construction described whenever the width of music is changed it is only necessary to detach the flange B from one of the kerfs, as a', and to rengage it with another for engaging the kerf in said roll having a rav dial entering-slot therein adapted to receive theuncut core of said roll and to be arranged in concentric relation thereto.

3. In a pneumatic player for musical instruments, the combination of a music-winding roll having a plurality of circumferential kerfs therein, of a guide-flange for alternatively engaging said kerfs and having an c ntering-slot therein for receiving the uncut core of said roll.

In testimony whereof I a'ix mysignature in presence of two witnesses.

JOSEPH COURVILLE.
